Art Points, commonly referred to as AP, are a game Mechanic in 异度神剑, similar to EXP and SP; however, instead of being used immediately to level up characters, they are left for the player to manually level up the arts they want, and can be 被救了 for as long as desired. AP can be earned by battling and discovering Landmarks. A maximum of 999,999 AP can be held at any given time.
Using AP to level up arts increases their effectiveness. What this means is different for every art, however; damage dealing arts will increase in power upon leveling, and all arts (excluding the Monado arts) will be granted shortened Cooldown times.
Added effects may also become more potent upon leveling up, though this is also dependent on the art. Leveling pink arts will prolong the time an 敌人 suffers the Break status, but leveling green and yellow arts will not prolong the time that an 敌人 will suffer 倒地 or Daze. Orange arts will increase the time that their auras remain potent but, again, whether or not the actual effect of said aura will be improved depends on the art. The 发狂的 aura's Strength Up effect can be improved, but its 物理 Defense Down side effect will always remain at a 25% drop. Lastly, it should be noted that Monado 盾 is unique in that it is the only art to gain no bonuses or prolonged effects upon leveling up. Its effect of nullifying Talent Arts for 15 seconds will always remain the same, and it has no cooldown either. Instead, it is Monado Shield's level itself that functions as the upgrade for this art, as it can only block talent arts of an equal or lower level than itself.
Like experience points and SP, higher leveled 敌人 (compared to your party members) will yield more AP, and low-leveled 敌人 will yield very little. AP, EXP, and SP are calculated based on the lowest-level battle party member, and 敌人 defeated during a Chain Attack will yield 25% AP more than normal. The amount of AP gained from an 敌人 or upon discovering a location can be increased with the use of AP Up gems. Although quests will often give experience and money, you will not gain AP or SP upon completing a quest, nor will AP or SP be given upon leveling up.
AP cannot be spent if an Art has reached its maximum level, and the maximum can be extended with the use of Art Books. See Leveling Battle Arts for more information on this.
